  • Brake-pressure control system
    Patent number: 4720150
    Abstract: A vehicular braking system wherein the brake circuit for the rear axle operates at a reduced pressure compared to master cylinder pressure that is applied directly to the brake circuit for the front axle, is provided with a pump that operates continuously during braking to draw fluid from the rear brake circuit and deliver same to the front brake circuit to essentially eliminate hysteresis, typical to prior art braking systems, that results in overbraking of the rear axle when master cylinder pressure is being reduced.
